Duotone - colors - colour - tint - shade - tone - hue

 
Duotone is a technique in design and photography where an image is converted into just two colors, typically using contrasting shades or hues. This technique is often used to create visually striking and impactful images. The two colors used can be selected for their complementary or harmonious qualities, enhancing the image's mood or conveying a specific message. Duotone images can add a modern and artistic flair to designs, and they are commonly used in various forms of print media, advertising, and digital graphics.
